NOTES:
3. V_IN = input voltage to perform proper function.
4. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
5. Parts are 100% tested at +25°C. Over-temperature limits established by characterization and are not production tested.
